Topic: Alpha Channel Opacity
posted by Michael Watkins
archived on 29.4.2003
Its been stated over and over again how much faster vray material opacity is over standard material opacity. Especially where GI is involved. However there are compaints about the alpha channel with vray materials. Maybe the next version wil have this fixed. But untill then here is a work around
Use a Blend material
In the mask slot is where the opacity map should go.
the color of the leaves goes in one slot
and put a vray material wrapper into the other slot using it as a shadow matte option. I havent personally tested it but egz has and said it works
For archetectural Glass you can probably try a simular method here except throw in some reflections on the glass. Hope this helps. enjoy
